Materials move within the cell 's cytosol by diffusion, and certain materials move through the plasma membrane by diffusion. ... Diffusion: Diffusion through a permeable membrane moves a substance from an area of high concentration (extracellular fluid, in this case) down its concentration gradient (into the cytoplasm). Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.The cell membrane controls what goes in and out by having protein channels that act like funnels in some cases and pumps in other cases. ... Active transport requires energy, because protein machines actively grab molecules on one side of the membrane and push them through to the other side
A plant was placed in water containing black dye. After 24 hours the
plant was removed and sections were taken from the root and the
stem. In the root, cambium part will get stained and in the stem, cortex will be stained from dye so the correct option is D.
<h3>
What is cambium and cortex in plant root and stem?</h3>
Cambium is a layer of continuous dividing cells between xylem and phloem tissues which is responsible for the secondary growth of stems and roots. A cortex is an outer layer of a root or stem in a plant, located below the epidermis but outside of the vascular bundles.
The conduction (uptake) of water in a plant stem takes place through the xylem.
